Order by multiple columns not working as expected in MySQL?

Following is the syntax to order by multiple columns −

select *from yourTableName
order by yourColumnName1 DESC,yourColumnName2,yourColumnName3;

Let us create a table −

mysql> create table demo29
−> (
−> value1 int,
−> value2 int
−> );
Query OK, 0 rows affected (1.67 sec)

Insert some records into the table with the help of insert command −

mysql> insert into demo29 values(10,500);
Query OK, 1 row affected (0.15 sec)

mysql> insert into demo29 values(14,400);
Query OK, 1 row affected (0.14 sec)

mysql> insert into demo29 values(9,500);
Query OK, 1 row affected (0.12 sec)

mysql> insert into demo29 values(13,400);
Query OK, 1 row affected (0.11 sec)

mysql> insert into demo29 values(45,500);
Query OK, 1 row affected (0.14 sec)

mysql> insert into demo29 values(11,400);
Query OK, 1 row affected (0.10 sec)

Display records from the table using select statement −

mysql> select *from demo29;

This will produce the following output −

+--------+--------+
| value1 | value2 |
+--------+--------+
|     10 |    500 |
|     14 |    400 |
|      9 |    500 |
|     13 |    400 |
|     45 |    500 |
|     11 |    400 |
+--------+--------+
6 rows in set (0.00 sec)

Following is the query to order by multiple columns −

mysql> select *from demo29
−> order by value2 desc,value1;

This will produce the following output −

+--------+--------+
| value1 | value2 |
+--------+--------+
|      9 |    500 |
|     10 |    500 |
|     45 |    500 |
|     11 |    400 |
|     13 |    400 |
|     14 |    400 |
+--------+--------+
6 rows in set (0.00 sec)
